Book Synopsis Microbial Extracellular Polymeric Substances by : Jost Wingender
Download or read book Microbial Extracellular Polymeric Substances written by Jost Wingender and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial extracellular polymeric substances (EPS) are the key components for the aggregation of microorganisms in biofilms, flocs and sludge. They are composed of polysaccharides, proteins, nucleic acids, lipids and other biological macromolecules. EPS provide a highly hydrated gel matrix in which microbial cells can establish stable synergistic consortia. Cohesion and adhesion as well as morphology, structure, biological function and other properties such as mechanical stability, diffusion, sorption and optical properties of microbial aggregates are determined by the EPS matrix. Also, the protection of biofilm organisms against biocides is attributed to the EPS. Their matrix allows phase separation in biofiltration and is also important for the degradation of particulate material which is of great importance for the self purification processes in surface waters and for waste water treatment.
Book Synopsis Natural Organic Matter and Disinfection By-products Characterization and Control in Drinking Water by : Sylvia E. Barrett
Download or read book Natural Organic Matter and Disinfection By-products Characterization and Control in Drinking Water written by Sylvia E. Barrett and published by . This book was released on 2000 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many by-products of water disinfection that are still not fully understood and can be potentially harmful. In this volume all the current research in this area is discussed, along with an examination of the role of NOM (natural organic matter) and its relationship to DBP (disinfection by-product) formation and control in drinking water. Understanding the relationship of NOM to DBP may well lead to new techniques for analyzing and treating water and enable reasonable choices to be made for source-water protection, treatment plant process optimization, and distribution system operation to control DBP's. This volume emphasizes the characterization and reactivity of polar natural organic matter. It examines analytical methods which better characterize NOM and determines some of the polar and nonvolatile DBP forms. It presents innovative new methods, sich as capillary electrophoresis for haloacetic aceids and LC/MS for the identification of polar dinking water DBPs.

Download or read book TECHNEAU written by Christian Kazner and published by IWA Publishing. This book was released on 2009-06-14 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The best papers from the three-day conference on Safe Drinking Water from Source to Tap June 2009 in Maastricht are published in this book covering the themes of challenges of the water sector and adaptive strategies, treatment, distribution, risk assessment and risk management, sensors and monitoring, small scale systems, simulation, alternative water supply & sources, consumer involvement, and future drinking water. Worldwide, the water supply sector is facing tremendous challenges. Every new emerging contaminants and pathogens and aging infrastructures that are vulnerable for deliberate contamination pose a threat to the quality of water supplies. Shortage of good quality and readily treatable resources is increasing due to global warming, urbanisation and pollution from agriculture and industry. Regulators and consumers are becoming more demanding. Techneau - the largest European project on drinking water - addresses these challenges by developing adaptive supply system options and new and improved treatment and monitoring technologies. Future system options to be studied are flexible, small scale and multi-source supplies, utilising non conventional resources like brackish ground water, treated wastewater and urban groundwater.

Book Synopsis Organic geochemistry of natural waters by : E.M. Thurman
Download or read book Organic geochemistry of natural waters written by E.M. Thurman and published by Springer Science & Business Media. This book was released on 1985-04-30 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written as a reference on organic substances in natural waters and as a supplementary text for graduate students in water chemistry. The chapters address five topics: amount, origin, nature, geochemistry, and characterization of organic carbon. Of these topics, the main themes are the amount and nature of dissolved organic carbon in natural waters (mainly fresh water, although seawater is briefly discussed). It is hoped that the reader is familiar with organic chemistry, but it is not necessary. The first part of the book is a general overview of the amount and general nature of dissolved organic carbon. Over the past 10 years there has been an exponential increase in knowledge on organic substances in water, which is the result of money directed toward the research of organic compounds, of new methods of analysis (such as gas chromatography and mass spectrometry), and most importantly, the result of more people working in this field. Because of this exponential increase in knowledge, there is a need to pull together and summarize the data that has accumulated from many disciplines over the last decade.
Book Synopsis Uncharted Waters by : Anna Andersson
Download or read book Uncharted Waters written by Anna Andersson and published by Linköping University Electronic Press. This book was released on 2021-02-15 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. In this thesis, a part of the unknown DBP fraction is investigated, covering a wide range of non-volatile, chlorine/bromine-containing DBPs. The goals were to investigate how the compositions of these DBPs differ between water treatment plants, how their occurrence changes in the distribution system until reaching consumers and how new treatment techniques can reduce their formation and toxicity. To analyze unknown DBPs, a non-targeted approach adopting ultra-high-resolution mass spectrometry, Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), was used, where the mass of molecules is measured with such accuracy that the elemental composition of individual DBPs can be calculated. A panel of bioassays was used to assess the combined toxic effects from these DBP mixtures. The results show that the formation of these DBPs to a large extent was specific to each water treatment plant and that local conditions influenced DBP formation, based on e.g., the abundance of organic material with certain chemical structures, bromide and disinfection procedure and agent (chlorine or chloramine). The DBPs were detected in both chlorinated and chloraminated water and in all tap water samples, demonstrating that they are part of human exposure. The number of DBP formulae decreased and the DBP composition changed between drinking water treatment and consumer taps, suggesting that DBP exposure to consumers is not necessarily resembling measurements at the treatment plants. Evaluation of new treatment techniques showed that suspended ion exchange and ozonation have potential to decrease the formation and toxic effects of DBPs and that the removal of organic matter can influence qualitative aspects of DBP formation, such as the proportions of chlorine-containing (less toxic) versus bromine-containing (more toxic) DBPs. Through increased knowledge about the role and relevance of non-volatile DBPs, this work can contribute to future monitoring and actions to reduce the health risks associated with DBPs in chlorinated or chloraminated drinking water. Desinfektionsbiprodukter (DBP:s) är potentiellt giftiga ämnen som bildas när dricksvatten renas med desinfektionsmedel såsom hypoklorit eller monokloramin. En stor del av exponeringen är ännu okänd och hittills kända DBP:s kan inte förklara de hälsorisker som förknippats med klorerat dricksvatten i epidemiologiska studier. I avhandlingen undersöks en relativt okänd fraktion av DBP:s som utgörs av icke-flyktiga, klor/brom-innehållande ämnen. Målen var att undersöka hur dessa DBP:s varierar mellan olika vattenverk, om de förekommer hos konsumenter och hur nya vattenreningstekniker kan minska dess bildandning och relaterad toxicitet. För att mäta okända DBP:s användes ultrahögupplöst masspektrometri (Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS)), med vilken massan hos molekyler kan bestämmas så exakt att atomsammansättningen för enskilda DBP:s kan räknas ut. En serie effektbaserade metoder som bygger på biologiska testsystem användes för att mäta kombinerade toxiska effekter från de studerade biprodukterna. Resultaten visar att största delen av bildade DBP:s var unik för varje vattenverk och att lokala förutsättningar påverkar vilka DBP:s som bildas, till exempel om det finns organiskt material med särskilda kemiska strukturer, bromid eller vilket desinfektionsmedel (klor eller kloramin) som används. De studerade biprodukterna detekterades både i klorerat och kloraminerat dricksvatten och i samtliga kranvatten, vilket innebär att de bidrar till konsumenters exponering. Antalet detekterade DBP:s minskade och sammansättningen ändrades mellan vattenverk och konsument, vilket innebär att DBP exponeringen hos konsumenter inte är densamma som mäts på vattenverken. En utvärdering av nya reningstekniker visade att suspenderat jonbyte och ozonering har potential att minska bildning och relaterad toxisk effekt från DBP:s och att borttagning av organiskt material kan påverka kvalitativa aspekter av DBP bildning, såsom proportionerna av klorerade (mindre toxiska) och bromerade (mer toxiska) DBP:s. Genom ökad insikt om icke-flyktiga DBP:s roll och relevans kan detta arbete bidra till att förbättra framtida uppföljning och insatser för att minska hälsorisker kopplade till DBP:s i klorerat eller kloraminerat dricksvatten.
